I do not plan to stop using nic in my juice. When I tried to quit before I was cranky, depressed, unable to problem solve or make reasonably rapid decisions. I'm at 4mg nic and it suits me to a tee. There are too many studies out there now saying some nic in your system is desireable. I'm 72 heading for 73, have no signs of incipient alzheimer's and I'd like to keep it that way.
Nicotine is no worse for me than caffiene, I enjoy both. The hand to mouth and oral thing has been of much more importance in my being comfortable not smoking cigarettes. I smoked for 55 yrs the last 20 of them at 2 cartons a week and I stopped that the day my gear came, so I feel very comfortable with what I am doing now
